Drain is not taling the discharged water away

THe bosch diswaher is pumping out fine but the drain outlet is now not taking the water away fast enough and seems to be blocked.
A few attempts at cleaning the drain pipe into which the outlet from the d.washer is hooked has not solved the problem. It used to work fine. Is the only reason for overflow a restriction in the drain outlet. A lot of dirt and grit has aleady been cleaned out.

Check your hose by running a coathanger through it and, don't forget to check the vacuum breaker hose also
if you just installed a new garbage disposal did you remove the plug in the outlet of the new GD before you conected the hose to the DW? look into the GD when the DW is draining and look for the discharge stream

Check the following.
1. The drain hose has to be discharging at a high enough point to prevent water flowing back into the machine.
2. Make sure your drain hose is not twisted or kinked.
3 . Make sure your drain line is not blocked push a flexible hose down it to dislodge any fat/debris
4.If your drain line discharges into a shared drain with another appliance i.e. garbage disposal make sure it is not blocked.
5. You may have a blockage at the inlet to the pump which would slow down the pumping rate,
Since you mentioned the mushroom shaped float allowing the washer to empty this may be defective.

It is a common fault that the drain fails to work in most machines in a period of time and is the most problematic fault in a washing machine. In all occasions it is important that your observation is most important and so is vital to the identification /rectification and solution. If you have noticed that water has leaked then as the drain hose pump/valve and fittings are located on the underside of the machine it is important that you look for possible leaks here. In some cases the drain hose would be clogged at the drain end to outlet of the house and so there will be back flushing resulting in overflow to the outside. Also the drain pump/valve can be clogged. Now remove the drain hose clamps and remove the drain pump/valve, clean the drain pump/valve, use back flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced.If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

I agree with you, I cannot see how any repair to a Bosch diswaher would justify or require it to leave your site let alone going to a repair shop. These (as any other manufacturer) are designed to be serviced in the home. To address the problem I would need more detail and clarification. Is the issue that the drain pump runs constant ? Does the tub get drained of water ? Let me know as much as you can and I should be able to assist you...depending on your mechanical abilities/comprehension. Please verify the model is indeed a Bosch SHV46C03. Thank you.

There is a chance the drain hose has buildup within it and needs to be cleared out. This will take about an hour.

Steps:

1- Unplug the electrical cord on the washer from the wall outlet.

2

Unfasten the hot and cold water
hoses from the water lines after you shut off the water valves. Use a
pair of slip-joint pliers to turn the hose fittings counterclockwise to
remove them.

3
Pull the washing machine far enough away from the wall so you can comfortably work on the rear of the machine.

4
Locate the access panel toward
the bottom left side of the back of the washer. Use a nut driver to
remove the nuts that secure the access panel, and remove it.

5
Find the water pump, which will have two hoses attached to it.

6
Identify which hose is the drain
hose by tracing it to the outside of the machine. The pump may also be
labeled "Inlet" and "Outlet." The drain hose is attached to the outlet.

7
Squeeze the clamp that secures
the end of the drain hose to the water pump, using a pair of slip-joint
pliers. Remove the end of the hose from the pump.

8
Insert a plumbing snake into the
end of the hose and twist the snake as you feed it through the hose.
After approximately 10 feet of the snake is fed through the drain hose,
you should see the snake and the clog come out the other end of the
hose.

9
Reattach the drain hose to the
water pump and replace the access panel. Reconnect the water hoses and
turn on the water valves. Push the washer back against the wall and plug
in the electrical cord.

Hello,
The problem is that the dishwasher discharges the water very rapidly...
Your drain pipe is either too small or partially plugged to the point that the water cannot get away fast enough...
You probably need to have the drain pipe cleaned, or aget some drain cleaner to put down it.

Same problem, so went out and bought a new bosch. Problem with the S510 was cured by lubricating the pump out motor bearings with a squirt of WD 40. If you don't know which pump, follow outlet hose to pump outlet.Les

you probably have something stopping the drain pump operating (like a tooth-pick or piece of plastic that won't break down in water) its a take it to pieces job i'm afraid but if you are fairly mechanically adept you can do it yourself. the drain pump is quite small and nearby to the drain outlet- you need to remove the case and release the drain from inside the unit- remove the pump itself and you'll prbably find somthing stuck in it- remove and re-assemble. In the meantime DO NOT use the dishwasher as you will 'burn out' the motor as the pump rotors are jammed.
Hope this helps
